Hi all, slowly reading the Parametric-vm spec. With my ASM hat, "As a structural constraint, it is illegal for a CONSTANT_Parameter constant to be unused."
This is different of all other CONSTANTs and doesn't work well with the idea that you can patch a classfile by copying the existing constant pool and replace only the method(s) you want, because if i replace a parametric method by a non parametric one, the existing CONSTANT_Parameter will stay in the constant pool with no reference to it anymore. Being able to patch a classfile like this is very important in term of speed for some transformers / agents. If the VM is able to find that a CONSTANT_Parameter is unused, instead of throwing an error, why not ignoring it ? Rémi
